Abstract:

In this review,the advantages and disadvantages of different biochar preparation methods,and the effects of biochar on soil physical and chemical properties and roots and rhizosphere microorganisms of facilities vegetables,and focuses on the effects and mechanisms of biochar on water and fertilizer utilization rate,vegetable field hazards and greenhouse gas emissions,and systematically elaborates on the agricultural and eco-environment benefits of biochar application in facility vegetable were summarized. The analysis was conducted to assess the impact of biochar on enhancing vegetable yield and improving quality. The future application of biochar technology in facility agriculture in China was also prospected.

Key words: biochar, preparation method, facility vegetables, soil improvement, ecological benefits, yield, quality
